INDOOR UNIT
Every unit includes a well-insulated cabinet, copper tube/alu-
minum fin coil with interlaced circuiting arrangement, 2"
throwaway filters, adjustable TXV’s and centrifugal blowers.
Blower motors and drive kits are ordered separately. Power
wiring for blower motor is field supplied.
The controls include 208/230/460 or 575 volt transformer,
blower motor contactor and relay, and a low voltage terminal
block.
The units are shipped in the vertical position ready for field
installation. For horizontal installation, the blower module can
be repositioned in the field as shown on pages 3 and 6 for
maximum flexibility.
ACCESSORIES INDOOR UNIT
(FIELD INSTALLED)
• Supply Air Plenums and Return Air Grilles (expanded
metal) accessories are available for free-standing indoor
(15 Ton units only) units located in the conditioned space.
Both accessories are finished to match the exterior of the
basic unit, and both can be applied with either vertical or
horizontal units. The supply air plenums are fully insulated
and have double-deflection, adjustable grilles.
• Base Sections are available to raise vertical indoor units
above the floor. Outdoor air may be introduced through
these bases by cutting an access opening for the out-
door air duct connection. These bases are finished to
match the exterior of the basic unit. They may have to be
insulated in the field for certain applications.
• Suspension Kit is available for indoor units installed hori-
zontally.
• Manual and electronic two stage thermostats are avail-
able for cooling applications.
• Both thermostats have a two-position fan switch, AUTO
and ON to provide intermittent or continuous blower
operation.
